Remember this video of a “holographic” cat on the iPhone created by David Oreilly?

Cool stuff for sure, but it wasn’t actually real and was just put together as a demo.

But now that the iPhone 3GS comes equipped with a digital compass, the “iHoligram” as it’s called is now a reality. The video below isn’t as eye-catching as the concept video above, but it’s certainly a solid start and should be available in the iTunes App Store in a few days. A forum commenter on MacRumors opined that the app will include 5 items — “a running ninja, a walking mech, a jeep (best for seeing the anaglyph effect), a cat and that helicopter + air fighter scene.”
